A 23-year-old male undergraduate presented with a history of recurrent constipation since childhood. He observed that the duration of constipation had progressively increased over the past decade with no known relieving factors. He has always had abdominal distension, which had also increased significantly over the past couple of years. He has had no episodes of bleeding per rectum. Examination revealed a young man with gross abdominal distension with tympanic percussion note and no palpable masses or organomegaly. The rectum was empty on digital examination. Plain abdominal radiographs revealed a markedly distended large bowel.

An abdominal computed tomography (CT) scan was performed [Figure 1].{Figure 1}

Question 1: Which features can be seen on the CT scan?

Question 2: List 3 possible differential diagnoses?

He had laparotomy, which revealed a hugely dilated sigmoid and descending colon with collapsed rectum. The transverse colon and the ascending colon were of normal calibre and exhibited normal peristalsis [Figure 2].{Figure 2}

He had resection of the markedly dilated and redundant sigmoid colon and a divided colostomy as the first-stage operation. The remaining sigmoid colon and the rectum were resected at the second-stage operation 5 months later followed by colo-anal anastomosis. Histopathology of the resected rectum is shown in [Figure 3] and [Figure 4].{Figure 3}{Figure 4}

Question 3: List two classical features in [Figure 3] and [Figure 4].

Question 4: What is the final diagnosis?

He was followed up for three years in good condition with no constipation and good anal sphincteric tone.

 Discussion



Hirschsprung's disease is a congenital condition arising from absence of enteric ganglion cells of the myenteric plexus as well as the submucosal plexus. It may affect a variable length of the large intestine but typically presents with constipation from birth necessitating treatment in infancy or early childhood. Ignorance of the disease, particularly in ultra-short segment involvements, could lead to endurance of chronic constipation, leading to presentation in adulthood as in the index case. Treatment usually consists of resection of the affected segment of the rectum and colon, followed by restoration of intestinal continuity with a colo-anal anastomosis using varieties of techniques. A preliminary colostomy as in the index patient is often necessary in long-standing cases. Public health information on this condition is important in our setting.
